How exactly the valve is made

Valve manufacturing process characteristics

Lead:The first few valve parts,simple structure,accuracy in general,are simple parts in the machinery industry,but the valve core sealing parts are particularly demanding.Valve manufacturing process is complex,technical difficulty is also large,which process characteristics we need to pay attention?
1.Make the material

Due to the wide range of valve specifications,the application of the valve in various fields of national economy,its use varies widely,such as high temperature and pressure,cryogenic cryogenic,flammable,highly toxic and corrosive media and other working conditions,the material of the valve Harsh requirements.

In addition to cast iron,carbon steel,alloy steel,but also extensive use of CrNi stainless steel,CrMoAl nitrided steel,CrMoV heat-resistant steel,CrMnN acid-resistant steel,precipitation hardened steel,duplex stainless steel,low temperature steel,titanium,Monel alloy,Due to Cornell alloy,Hastelloy and G0CrW cemented carbide.These high-alloy materials,casting,welding,processing performance is poor,to the manufacturing process has brought great difficulty.Coupled with these materials are mostly high alloy,high strength,high hardness of precious materials,from the material selection,preparation,procurement,there are many difficulties.Some materials due to the use of small,difficult procurement procurement.
